Shear-sensitive thixotropic paste seals threaded joints in ...

FORMULA-8 is engineered as a shear-sensitive, aqueous, PTFE thixotropic paste that sheets into PTFE strings when torqued. It is an irreversible process that seals over the entire thread length which means fine threads in instrumentation systems are completely sealed. Replaces PTFE tape and corrects challenges associated with tape.
